After purchasing your package(s) and receiving an email to create your TAG account, you will be able to log in to your TAG Portal. First, select the presale package you purchased and you can begin entering the card ID information of your intended submission. When your cards are registered and confirmed in the TAG Portal, your submission kit will ship.
A video demonstration on how to best utilize the Portal can be found here: https://youtu.be/q1591WTrRWQ
